My hope is that doesn't mean you can still digitize media that's on a dying format and that can still be used in CDL. Like if you owned a legitimate copy of a movie on betamax that format has been dead for years you can't buy a new betamax player you can digitize that before the tape becomes unreadable. That's been explicitly in copyright law last I looked and it's just a matter of defining what media is "dying" enough to count under this.
